Eight keys are available for operating the ULTRAMAT 23. These keys
have the following meanings:
Meaning
Measure Measure; abort input operations; leave input mode (from
any menu level); switch from input mode to measuring
mode and code analyzer again (cf. Section 5.6.1)
AUTOCAL Automatic calibration; activation of calibration with ambient
air or nitrogen
Pump Switch internal sample gas pump on/off
Escape In input mode: return by one menu level or cancel current
input or cancel calibration*
Arrow upwards Increase selected digit; select previous menu item
Arrow downwards Reduce selected digit; select next menu item
Arrow to right Move input cursor by one position to right (cyclic, i.e. the
cursor is set to the left edge when the right edge has been
reached)
Enter In measuring mode: switch over to input mode
In input mode: import entered parameters or call a menu
item
You can use the arrow keys to modify numerical values by increasing
or decreasing the digit at which the cursor is located. The digits are
modified continuously, i.e. 0 and 1 follow again after digit 9, and you
can also decrement to 9, 8... following digit 0. The analyzer outputs the
value FFF... if incorrect numbers are entered.
Use of the MEAS, ESC and ENTER keys is described using examples
in Section 5.5. Use of the CAL and PUMP keys is described in Section
5.11.
